After this call, Merrifield was never mentioned on an Intel earnings call. At Investor Meeting 2013, Intel did not talk about how many phones it planned to ship in 2014, just tablets. And, of course, it's been 2 months since the Merrifield platform "launched" and the only design we have seen is an FFRD.
Note also that Intel plans a dual core Silvermont SoC with very high integration (SoFIA 3G) in Q4 2014 and a quad Silvermont (SoFIA LTE) in Q1 2015. Note also that Intel felt the need to get these to market quickly enough that TSMC was employed to build the chip.
Also note that instead of pushing Merrifield into low cost Android tablets, Intel is pushing Bay Trail across the stack.
I think from these facts one can draw a reasonable conclusion as to how much traction Merrifield will get.
